- * The set_memory_* API can be used to change various attributes of a virtual
- * address range. The attributes include:
- * Cachability   : UnCached, WriteCombining, WriteThrough, WriteBack
- * Executability : eXeutable, NoteXecutable
- * Read/Write    : ReadOnly, ReadWrite
- * Presence      : NotPresent
- *
- * Within a category, the attributes are mutually exclusive.
- *
- * The implementation of this API will take care of various aspects that
- * are associated with changing such attributes, such as:
- * - Flushing TLBs
- * - Flushing CPU caches
- * - Making sure aliases of the memory behind the mapping don't violate
- *   coherency rules as defined by the CPU in the system.
- *
- * What this API does not do:
- * - Provide exclusion between various callers - including callers that
- *   operation on other mappings of the same physical page
- * - Restore default attributes when a page is freed
- * - Guarantee that mappings other than the requested one are
- *   in any state, other than that these do not violate rules for
- *   the CPU you have. Do not depend on any effects on other mappings,
- *   CPUs other than the one you have may have more relaxed rules.
- * The caller is required to take care of these.

-/*
- * For legacy compatibility with the old APIs, a few functions
- * are provided that work on a "struct page".
- * These functions operate ONLY on the 1:1 kernel mapping of the
- * memory that the struct page represents, and internally just
- * call the set_memory_* function. See the description of the
- * set_memory_* function for more details on conventions.
- *
- * These APIs should be considered *deprecated* and are likely going to
- * be removed in the future.
- * The reason for this is the implicit operation on the 1:1 mapping only,
- * making this not a generally useful API.
- *
- * Specifically, many users of the old APIs had a virtual address,
- * called virt_to_page() or vmalloc_to_page() on that address to
- * get a struct page* that the old API required.
- * To convert these cases, use set_memory_*() on the original
- * virtual address, do not use these functions.
